Truck-Lite 40242R Super 40 Incandescent Red 4" Round Stop/Turn/Tail Light (12V, Black ABS Flange Mount, PL-3 Connection, Sealed Lamp)
Upgrade your commercial vehicle's rear signaling with the premium, theft-resistant Truck-Lite 40242R Super 40 Series Stop/Turn/Tail Light. This 4-inch round, red incandescent lamp is engineered for heavy-duty fleet trucks, trailers, and utility vehicles. It features Truck-Lite’s legendary uniquely designed shock-mount technology, which isolates the dual-filament bulb from harsh road vibrations and impacts to drastically extend its operational life.
Rather than relying on a separate rubber push-in grommet, the Truck-Lite 40242R is built with a permanently integrated, high-impact black ABS plastic flange. This structural design allows you to flush-mount the light directly onto your vehicle's panel cutout via a secure surface-screw application, keeping the light tight and secure while deterring tampering on the highway. Sonically sealed and 100% watertight, this premium 12V lamp utilizes an industry-standard PL-3 connection and is backed by an extended 3-year limited manufacturer warranty.
